WHY MUNICIPALITIES SHOULD APPLY MANHOLE COATINGS IN-HOUSE
INDEPENDENCE HAS NEVER BEEN EASIER Municipalities, busy as they are, have often sought outside help to rehabilitate wastewater infrastructure and protect these systems against future wear. This is especially true for manholes, which dot the urban landscape right before our eyes and just below our feet, enabling essential services so that the rest of us don’t have to think twice when we turn on the tap or flush the toilet. Nobody can blame municipalities for deferring to specialized coatings experts, but relying on third-party contractors no longer delivers the same cost-efficiency or productivity. Today, municipalities can invest in in-house capabilities …

How To Install A Secondary Containment System On Your Geotextile Fabric?
The recent increase in domestic oil production has focused on the environmental hazards and potential cleanup costs posed by oil spills in drilling, refining, and storage operations and the need for a safeguarding or secondary containment method in addition to the primary containment system. The traditional approach has been to amass native soil into berms creating enclosures enwrapping drill sites, pump stations, and storage tanks. This approach is practical in slowing the migration of spilled material. However, it does not prevent soil absorption and contamination, which means that the site will need a costly remediation process in the event of …
Flexible Coatings For The Protection Of Marine Structures
Protecting offshore structures from corrosion and abrasion damage is a constant and expensive challenge for operators. Both abrasive and exceptionally corrosive, the marine environment is extremely harsh on marine structures like offshore platforms and rigs and ocean-going vessels, all of which are significant investments for the businesses that operate these structures. Corrosion affects all structures in the marine environment. The marine environment can be extremely harsh on surface coatings, both in terms of wear and application. The most affected areas are superstructures, decks, ballast tanks, chains, and anchor wells. These areas are subjected to salt water, chemical chemicals, and abrasion. …
Polyurea Saves The Day At Aging Water Treatment Facilities
Investment in infrastructure is a hot issue throughout this part of the United States. During his presidential campaign candidate, Trump said he would unveil an ambitious infrastructure bill within the first hundred days as president but nothing has been implemented so far. The plan was initially put forward that included $137 billion in federal tax credits for private companies that invest in transportation projects. This, Trump said would bring about an investment of $1 trillion over the next 10 years. Senate Democrats oppose the plan, and in January, they released the Senate’s individual “blueprint” of infrastructure expenditures that call for trillions of dollars …
The Ever Expanding Pipe Coating Industry
The continued growth of the pipe coating industry requires and relies upon successfully bridging the current disconnect and working together to deliver quality applied coatings. In the last twenty or thirty years, the oil and gas pipeline coatings industry has seen a lot of changes. From the days of coal tar coatings with relatively little oversight, the rapid growth of advanced coatings, specifically fusion-bond epoxy (FBE) with very specific application procedures, has led to highly detailed coating specifications covering every aspect of the process. For example, when I started in the late 1990s, coating specifications were maybe four or five pages. It …
A Monolithic Approach To Primary And Secondary Containment Using Polyurea
Advanced flexible polyurea coatings applied directly to the substrate or geotextile liners provide seamless containment for facilities and field applications. Traditional coatings have been too inflexible and not sufficiently elastic to accommodate ground, concrete, or metal substrate movement when used for primary or secondary containment. This defect can lead to cracks or holes forming in both the substrate and the coatings, compromising containment jobs. Tough monolithic flexible coatings such as polyurea resolve this issue for contractors and engineers. When applied directly to concrete or metal surfaces, polyurea reinforces and protects the underlying substrate and can bridge gaps or cracks of …
Stopping Corrosion, Slowing Bullets: The US Military Has Found An Indestructible Tool In Polyurea
New polyurea coatings being tested by the U.S. Naval Research Laboratory can create a rubber surface that not only stops corrosion but improves the ballistic protection of armored amphibious assault vehicles. The reported advance could provide a quantum leap in shielding the U.S. Marine Corps’ AAV fleet from two critical threats at once, developers say. The U.S. Marine Corps’ mighty Amphibious Assault Vehicles (AAVs) remain vulnerable to corrosion when their paint cracks under intense duty. New elastomeric coatings may change that. They seem to have solved the corrosion problem. And with a negligible increase in weight, they also provided better …
It’s Time To Cash In On The Coatings Market
In the ever-expanding polyurea coatings market, the margin of error is superlatively narrower than for conventional coatings. And while opportunities abound for contractors to jump on the polyurea bandwagon successfully, the growing variety of applications and the superior properties of sprayed polyurea need particular attention given to the dispensing machinery involved. The following explanation can quickly help any applicator understand the polyurea application process, the interplay between the various pieces of equipment, and the important design considerations of the pump, hoses, and spray gun. This experience can help open the door to a whole new market for coatings businesses that …
POLYUREA RECENT ADVANCES FOR USE WITH PIPELINE REHABILITATION
Polyurea technology is not new to the pipelining industry, with basic applications dating back more than 30 years. Much of this work was performed by hand spraying or simple robotic systems for individual joint segments of pipe. In the United States alone, it is estimated that over $1 trillion will be required over the next 25 years to restore buried water and wastewater lines due to age and deterioration. Almost $350 billion will be required to restore potable and drinking water lines. This does not include all of the buried and in-use steam and chemical pipelines affected by age. While …
Primer For Prevention Of Industrial Facility Corrosion
For industrial centers, such as manufacturing plants, processing centers, and storage tanks, avoiding corrosion is a seriously crucial functional and safety concern. Nevertheless, direct exposure to chemicals, chlorides, wetness, and humidity, whether indoors or out, is a destructive mix that can reduce the service life of everything made from steel, such as tanks, pipelines, sidewalks, center structures, and external facilities. Since steel corrosion is a serious concern in such installations, re-priming and repainting typically occur every couple of years. While industrial primers represent an important structure for paints and coatings in severe environments, they have historically been unable to handle …
